Silence the Logs: VirtualBox

VirtualBox is chatty by default — it logs everything.
Here’s how to shut it up.

Where logs live

• Global: ~/.config/VirtualBox/
• Per VM: ~/VirtualBox VMs/YourVM/Logs/

Step 1: Clean up the past

First, stop all VirtualBox processes.
Then delete all *.log files in the paths above.

Step 2: Stop future logging

You’ll need to set a few environment variables to disable logging entirely.
There are two ways to do it:

Option A: Temporary (per session)

export VBOX_RELEASE_LOG_DEST=nofile
export VBOX_LOG_DEST=nofile
export VBOXSVC_RELEASE_LOG_DEST=nofile
export VBOX_GUI_SELECTORWINDOW_RELEASE_LOG_DEST=nofile
virtualbox

Option B: Permanent (for all users)

cat >> /etc/environment <<\EOF
VBOX_RELEASE_LOG_DEST=nofile
VBOX_LOG_DEST=nofile
VBOXSVC_RELEASE_LOG_DEST=nofile
VBOX_GUI_SELECTORWINDOW_RELEASE_LOG_DEST=nofile
EOF
